EMIL STAHL, OF NEW YORK, N. Y.

BOTTLING-MACHlNE.

SPECIFICATION forming part of Letters Patent No. 538,290, dated April30, 1895. Application filed August Z3, 1894. Serial No. 521,082. (Nomodel.)

To LZZ whom t may concern:

Be it known that I, EMIL STAHL,-of New York city, New York, haveinvented an Im- -proved Bottling-Machine, of, which the following is aspecification.

This invention relates to an improved machine for charging bottles withsirup and aerated water, and also for corkin g the bottles.

In the accompanying drawings, Figure l is a side elevation, partly insection, of my irnproved bottling machine. Fig. 2 is a plan thereof;Fig. 3, a horizontal section on line 3 3, Fig. l. Figs. 4 and 5 arehorizontal sections of the valve b on line et 4, Fig. 6. Fig. 6 is avertical section of the valve on line 6 6, Fig. 5.

The letter d, represents the frame of the ,bottling machine providedwith a seat a',

adapted for the reception of the bottle A to be charged.

b, is the filling head or Valve,provided with four ports b', b2, b3, b4,and containinga fixed valve plug c, which is provided with a centralbore e', three radial ports c2, c3, c4, and a cut away section c5. Thevalve b, maybe revolved backward and forward by a handle b5, and issupported upon an annular seat CZ (Fig. 6), screwed upon the lower endof plug c. The plug c, is provided with a downwardly extending threadedtube o9, engaging a cup c6, and containing a packing c7, adapted `toengage the head of the bottle A. At its upper end,vthe plug c, isprovided with perforated trunnions o8, hung in the slotted arms e', of aforked lever e, which is pivoted toframe a, at e2. The lever e, isnormally held down by a spring d3, and may be raised by a hand lever e4,pivoted to frame a, at e5, and connected to the lever e, by link e6. Arest a6, limits the downward motion oflever e. Through the perforatedtrunnions o8, pass the xed guide rods f, secured to the laterallyextending lugs a2, f frame d, and adapted to guide the plug c, andconsequently the valve b, in a vertical direction.

g, is a sirup gage, connected to the sirup tank (not shown in thedrawings) by tube g', that contains check valve g2. The gage g, is alsoconnected to the port b, of valve h, by tube g3. luto the top of gage g,projects a vent tube h, connected by iiexible pipe h', to the port h2,of valve b. The tube 71., is Vertispring as.

cally adjustable, so that it may be projected into the gage g, to anydesired distance,in order to alter the capacity of -the gage and thequantity of sirup charged into the bottles. To this effect the tube h,passes through a stuiing box h2, secured to the upper end of the gageand within which it may be slid up or down. The end-of tube h,constitutes the seat for a float or ball valve h3.

lhe aerated or charged water is fed from a carbonator (not shown in thedrawings). by tube t', to the port b3, of valve b.

j, is the corking plunger which is adapted to enter the centralperforation c', of plug c, and which is provided with teeth j', toconstitute a rack. This rack is engaged by a toothed segment k, adaptedto be oscillated around its pivot k', hyhandle k2.

The operation of the machine is as follows: The lever c, is raised byhandle e4,and a bottle A is placed upon a cushion a4, of seat a', afterwhich the handle is released, so that the Valve is pressed upon thebottle neck by The cork Bis then pressed into the bore c', of plug c,(Fig. 6) by a partial descent of the plungerj, but without obstructingthe ports in the plug. The Valve h, is next revolved into the positionshown in Fig. 5, in which the sirup from gage g, is admitted by tube g3,and ports h4, c4, while the aerated water is admitted from tube i, andports h3, c3, into the lower end of bore c', and thence into the bottleA. As the bottle is thus illed, the displaced air is ejected from thebottle through bore c', ports c2, b2, and tubes h', 7L, into 'gage g, tobearl upon the sirup and force it through pipe g3, into the bottle,while it will also serve to keep Valve g2, closed. Of course, the iioath3, will gradually descend with the level of the sirup in the gage toopen the vent h. After the bottle has been properly charged, the valveb, is revolved into the position shown in Fig. 4, so as to close theports b4, b3, and cut o `the supply of sirup and of aerated water. Atthe saine time, the vent 71, h, is made to communicate by port b2, cutaway section c5, and port b', with the atmospheric air. Thus vthepressure of the sirup in the sirup tank will be free to open check Valveg2, and the Sirup will ow into gage g, until the oat h3, is raisedagainst the Vent h, when the further ingress of sirup will be stopped.

ICO

Thus the gage has been charged with the de sired quantity of sirup,ready to be discharged during the next filling operation. While the gageis lled, as described, the corking plungerj, is pressed down to its fullextent, to force the cork B cutof the perforation c,and into the bottleneck. The lever e, is then raised by means of its handle e, to raisevalve b, otf the bottle neck, without however raising the plunger. Thusthe cork is held in the bottle by the plunger and may be secured by theusual bail A', when the plunger is raised and the operation iscompleted.

In order to adapt the machine to fill bottles of different sizes, Iprefer to use interchangeable seats a', a5, having bottoms sunk to agreater or less depth, to accommodate bottles of different heights.

The principal advantages of my machine are, that it utilizes thedisplaced air from the bottles to force the sirup into the bottle.Moreover the quantity of sirup to be filled into the bottle isaccurately gaged, and may be readily varied.

The machine works rapidly, requires little power and creates no waste.

1. The combination in a bottling machine of a rotary filling head havingfour ports with a sirup tube,a water tube and a vent tube connected tothree of the ports, and with a valve plug having radial ports adapted toregister with three of the valve ports, and a cut-away section, adaptedto connect two of the valve ports, substantially as specified.

2. The combination of a Valve, with a lever e, a pivoted valve plughaving perforated trunnions, guide rods engaging the trunnions, acorking plunger engaging the plug, and charging tubes connected to thevalve ports, substantially as specified.

3. The combination of a valve, with a lever e, a valve plug pivotedthereto, a corking plunger engaging the plug, and with a vent tube, aSirup pipe and a Water pipe connected to the valve ports, substantiallyas specified.

4. The combination in a bottling machine, of a sirup gage with avertically adjustable vent pipe entering the same, and adapted to beprojected to a greater or less extent into the gage, and a float adaptedto close the month of the vent pipe,substantially as specitied.

5. In a bottling machine the combination of the following elements: arotary valve, an inclosed plug, a corking plunger, a water tube, siruptube and vent tube connected to the valve ports, a sirup gage connectedto the Vent tube and sirup tube, and a floatwithin the sirnp gage thatis adapted to close against the mouth of the vent tube, substantially asspecified.
